LOOM-SHUTTLE.

SPECIFICATION formingpart of "Letters Patent No. 729,615 dated June 2, 1903. Application filed February 17, 1902- Serial No. 94,391- (Noimodel) To whom it may concern.-

Beit known that I, JOSEPH E. LEMYRE, a citizen of the United States, and apgresident of Manchester, in the county of Hillsboro and State of New Hampshire, have invented new and useful Improvements in Loom-Shuttles, of which the following is a specification.

My invention consists in an improvement in loom-shuttles, and has for its object the prevention and saving of waste, which is at present a well-known incident to weaving with cop-filling. I need only mention two prolific sources of waste-namely, breakage of the cop, which is the separationof the butt of the I 5 cop from the body, due to the shock and impact of the picker-staff and entanglement of the cop-thread around the butt, which causes breakage of the thread and often the waste of the butt.

By means of the attachment which Ihave invented and which may be called a copseat, waste from such causes as the above is prevented.

I11 the drawings which illustrate an embodi- 2 5 ment of my invention, Figure 1 is a plan view of a shuttle, showing my improvement in cross-section; and Fig. 2 is a side view of the cop-seat detached. Fig. 3 is a section thereof.

A is the body of the shuttle; B, the spindle 3o spring-hinged at C in the usual manner.

D is a cop; E, a cop-support, preferably of smooth metal, having a hollow conical body terminating in the neck 6. I form also a slightly-flaring lip e 011 the conical shield E.

3 5 Aeoiled spring F, which I coil preferably in a conical helical form, so that the coils when compressed will rest within each other, is secured to the neck 0 in any desirable manner. The manner of use of my improvement is 4.0 as followsz'Theeop-seat, which consists of the shield E, and its spring-base F, is placed upon the buttd of a cop, which by reason of the conical shape of the cop-support E fits the support quite snugly. Then the spring F, neck 6, and cop D are slipped upon the spindle B and pressed down in the usual manner, the spring F coiling upon itself and pressing against the cop-butt d. This springpressure is resisted by the spring of the 5:1 spindle B, which is of the ordinary construction.

In the operation of the loom the unsupported cop-butt (1 often pulls away from the body of the cop, making a break, say, at the point (I. This break while not necessarily involving rupture of the thread nevertheless so tears down the structure of the cop as to render the whole useless except as waste, which may be partially rewound by machinery devoted to the purpose; or, as the cop becomes unwound in the progress of weaving cloth the centrifugal whirl of the thread, coupled with the sudden reversal of move ment of the shuttle, may cause one or two turns of the thread to be coiled around the cop-butt d, in which these turns become embedded or entangled, so that at the next succeedingpick the thread breaks in such manner that it possiblyfcannot be recovered. The portion of the cop remaining on the spindle then goes to waste; but with my new cop-seat in place such things are prevented. The pres sure of the base-spring F affords such support to the support E and the cop-butt (Z sustained thereby thatbreakage of the cop is made practically impossible In case also the thread tends to fling its loosened turns over the support E the flaring lip e guards against this tendency, and even if the thread should throw over tothe outside of the support E the latter is so smooth that the thread strips oif without resistance and does not break.

I prefer to construct the support E so that it fit's the cop-butt (Z closely; but it is obvious that the conical form of the support may be departed fromwithout sacrifice of all the beneficial results incident to its use.

I prefer to have internal bore of the neck 0 of such diameter that the end of the tube (1 on which the cop is built may enter therein while on the spindle B. I provide also the internal shoulder e at the base of the neck 6, so that when the support E is removed froin the spindle the shoulder e? will carry with it the tube (Z and strip the latter from the spindle. If the neck 6 is made to fit the spindle 13 too closely, the tube (Z is liable to bind and jam when the support E is removed. The clearance provided between the spindle and the neck 6 avoids this difficulty.

What I claim, and desire to secure by Letters Patent, is'- 1.
